ABSTRACT OF THE DISCLOSURE Disclosed is an apparatus for centering and driving a flexible disc which includes a rotatable spindle and a cone which is insertable through a drive hole in the disc and then into an opening in the spindle whereby the disc is contained between the cone and spindle. A plurality of upstanding centering fingers are mounted in the spindle, extended to the threshold of the spindle opening and equally spaced from the spindle center. The fingers engage the cone as it enters the opening and bend elastically responsive to further cone movement into the opening. The fingers, when so bent, urge the cone toward a centered relation with the spindle. The fin- gers are adapted to engage any unsupported portion of the disc positioned over the spindle opening, and to support such portion against bending re- sponsive to contact with the moving cone.
